Re Mac mini 2020 running Catalina
Just purchased the mini and migrated files from another mac. I set up the non apple email account and once it connected it erased all of the emails from the server for some reason. This has never happened to me before and I have migrated a lot of old macs to new ones.
Is there any way to get copies of these emails from the back up that I made prior to migration?
Hello,
If your Macintosh connects to the internet using ethernet then you could disconnect the ethernet cable. Alternatively if your Mac connects to the internet using Wi-Fi then you could temporarily unplug your Wi-Fi from power. This would allow you to start your Mac up without fear of it connecting to the internet. You could then follow the information in this Apple Support document to migrate messages out of Mail which you then could import into your newer Mac.
Thanks QuickPost, I hadn't thought of copying the messages to a different mailbox. If I do it carefully I shouldn't lose the emails.
Hello,
Does your previous Macintosh still have these email messages?
Yes. If I could safely email them to another account or export them but I am afraid to turn on the internet (for that computer) and open mail in case it just erases them as well.
Setting up mac mini for the first time and it erased all of my emails
